HOLDING DEVICE FOB, VEHICLE-TIRES.

Application lcd November 4, 1912. Serial No. 729,307.

To all whom it may concern.'

Be it known that I, FREDERICK F. PHIL- LIPS, a citizen of the United States, residing at Flushing, county of Queens, and State of New York, have invented certain new and useful Improvements in Holding Devices for Vehicle-Tires, of which the following is a full, clear, and exact disclosure.

My invention relates to that class of rims for vehicle tires in which the elastic tire itself is permanently mounted upon a plurality of plates so that parts or sections may be easily removed from or placedupon the rim and held in position thereon by means of clampin devices. This type of rimv and tire is usua ly employed in connection with motor trucks on which the tire itself is made solid in cross section and divided into blocks or'sections which are removable independently of each other.

he object of my invention is to produce a fastening or clamping device for the parts lof the tire which will not only render the tire or sections thereof easilyremovable, but willzclamp the same firmly and accurately in 'place at all times and under the great stresses to which such tires are subjected when in use.`

For a full and detailed description of different forms of my invention, reference maybe had to the following specification and to the drawing forming a part thereof, in

which Figure 1* is a side elevation of my improved rim; Fig. 2 is a transverse4 sectional view taken substantially on the line A- A, Fig. 1; and Fig. 3 is a similar transverse sectional view showing my invention applied to a rim having a single tire mounted thereon; Fig. 4 is an enlargedsectional viewsimilar to Figs. 2 and 3, but showing one side of the rim only; Fi 5 isa similar sectional view showing a m ifioation of thedeviee.

Referringleto the drawing, the numeral 1 'indieites t usual wooden felly` vof -the whee The numeral 2lindicate's the metallic felly .band Aor fixed rim secured the wooden fell Y Y A 'Idle numeral 3 indicates the base plate or lates of the tire and fthe, numeral v4 inldiate's the solid rubber tire comprising independently removable blocks mountedf'onV the'b'ase plates 3. The.fellyb'ax1d 2v is usuperxnanelitly attachedto the :felly v1 and forms an unyielding seat for the tire plates 3. As will be seen 1n the drawing, the felly band 2 is substantially the same width as the felly 1, while the outer edges of the tire plates 3 extend over or beyond the ledges of the felly band, their outer corners being beveled, as indicated at 5. The angle formed between the overhanging edges of the tire band and the edges of the felly band is partly filled by separate retainin and wedging rings 6 made preferably o substantially the same shape as said overhanging edges, the inner sides of said rings being beveled, as indicated, to form wedges with l vided with inwardly extending radial portions 9 which preferably'terminate in beads 10 which bear` against the felly. The Y' y grooved clamp sections 7 are held in position by means of bolts 11 which pass through holes therein and also through holes in the felly 1. These bolts may be of any form preferred, but I have shownfthe same consisting of the ordinary round bolt varietyl with the hexagonal nuts 8 at one end.

In case of two tires being used upon the same felly, I provide a central separating ring 12 which is beveled on its inner edges to correspond with the inclination of the bevel ofthe edges of the tire plates 3. It"

willbe seen that this provides a clam ing ring which holds the inner edgesof thev ase or tire plates with the same force as'applied to their outer edges. All the rings and bands referred to above are preferably endless, orfwithout cuts.-

. It will .be noted that the wedging 4rings 6jand 13 do not contact withthe inner'sur- Afaces of the adjacent tire plates 3, a smallspace being left to allow for slight varii .further` advantage inthe use -of the sepaations, in thee-sizes of the felly bands and toV i rable wedging rings results from the fact that the bolts 11 are relieved of radial strains, the outward pull ofthe tire plates being counteracted by the retaining action of the wedging rings, thereby preventing outward radial movement of the tire plates 3 independently of transverse' strains on the bolts 11 and the felly 1. The use of the wedging rings also does away with the necessity of special felly-bands with beveled edges so that standard wheels may be used without modification.

Having thus described these two forms of my invention, I do not Wish to be understood as being limited to details of design or arrangement of parts as herein set forth, for various changes may be made without departing from the spirit of my invention. For example, the tire base plates 3 may not be of the short length indicated, but may extend overa larger part of circumference of the wheel. In the same way the grooved clamping sections 7 may be made longer or shorter. However, for the sake of easy removability of separate pieces or blocks of the tire when worn or damaged, I prefer to make the clamping part referred to in sections as illustrated.

What I claim Letters Patent is:

1. A holding device for vehicle tires, com/ prising, a fixed wheel member, a tire having. a rigid base and extending laterally from the tire, a separate ring at the .side of the fixed member of the Wheel and adjacent vthe edge of the said base, and means engaging opposite sides thereof for/'drawing said tire base and ring respectively toward' each other radially.

2. A holding device for vehicle wheels, comprising, a fixed member, a tire having a rigid base, a laterally projecting margin, a separate ring at the side of the tixed member of the wheel, and means including opposed parts engaging on opposite sides to and desire to protect by draw the saine respectively toward each other radiallytiand devices for securing said holding means in position on said fixed member.

3. A holding device for vehicle tires, comprisin a fixed wheel member, a ytire base carrie thereby, a separate ring extending said tire base and ring Y laterally at the side of said fixed member, clamping means having a Wedge-sha groove for wedging said tire base and ring radially toward each other, and devices for securing said clamping means in position.

4. A holding device for vehicle tires, com lprising a fixed wheel member, tire lates aving beveled edges carried there y, a ring extending laterally at the side of fixed member, clamping means having a wedge-shaped groove for wedging said tire base and extending ring toward each other, and devices for securing said clamping means in position.

5. A holding device for vehicle tires, comprising a fixed wheel member, a tire having a rigid base carried thereby and extending laterally beyond said fixed member, a separate ring within the edge of said base and of less diameter than said fixed member, and means for clamping said tire base and ring toward each other radially. f

6. A holding device for vehicle tires, comprising a fixed wheel member, a tire `having a rigid base carried thereby and extending laterally beyond the fixed member, a separate ring at the side of said fixed member Within the edge of said base, the external diameter of said ring being less than the internal diameter of said base, means for wedging said tire base and said ring toward each other radially, and devices for holding said Wedging means in position.

7. A holding device for vehicle tires, comprising a fixed member, a tire having a plurality of rigid base plates, carried thereby and extending laterally beyond the fixed member, a separate ring at the side of said fixed ember Within the edges of said plate, the external diameter of said rin belng .less than e diameter of said ed member, and exte nal clamps carried by the fixed memberrfor forcing said ring and base plates toward each other.
